5) The ratio of area and perimeter of a square is 2 : 1 , then area of circle with diameter equal to diagonal of square is:

Let the measure of the side of the square be represented by .

Then the Area is given by and the perimeter by . But with the given proportion, . Hence which is to say .

The diagonal of a square with side measure is , hence the radius of a circle with diameter equal to the diagonal of the square is , in your case, .

The area of a circle with radius is . So in your case:
